Kupo Rotatable Ring Bolt 3/8"-16 × 14 mm (KS-156)

Overview

The Kupo KS-156 Rotatable Ring Bolt is a professional rigging accessory designed for securing safety cables, suspension systems, and tether points in film production, television, photography, theatre, and studio environments.

Constructed from durable steel, the KS-156 features a rotating ring design that allows the eyelet to pivot freely, helping reduce cable twisting and improving flexibility when attaching safety wires or rigging components. The bolt uses a standard 3/8"-16 male thread, making it compatible with a wide range of grip equipment, lighting fixtures, mounting plates, clamps, and rigging accessories that support 3/8"-16 threaded mounting points.

The compact 14 mm threaded shaft length makes it suitable for installations where a secure attachment point is required without excessive protrusion. Its robust construction makes it ideal for professional production environments where equipment safety and secure rigging practices are essential.
